In the first figure the electron
spectrometer ELS instrument appears on the left, ion mass spectrometer IMS
at the center and ion beam spectrometer IBS on the right. The high
voltage units HVU are between the IBS hemisphere and IMS cylinder.
The data processing unit DPU is a box below the spectrometers, and
actuator is below the DPU. A lot of wires can be seen around the
In the second figure the ELS and IMS cylinders from the back.
In third figure the IBS is on the very left. The bottom of the
IMS cylinder is in the center of the figure.
In the fourth and the last figure IBS hemisphere is on the
left. The HVU box is just between the IBS hemisphere and IMS
In the lower figure red lines shows the electron field
of view of the ELS instrument. The blue lines shows the
corresponding ion field of view of the IMS and IBS. Note that in IBS
only central fan is show using several lines while the side fans are
marked using only single lines.
